Run gets into a little trouble when she forgets to put on her panties in the morning. Yūko goes into a little panic when Run collapses, though it turns out to be just a bit of sleep deprivation. After having to deal with heavy rain, the girls spend the evening at Nagi's house to dry off. While Run and Nagi take a bath, Tōru forces Yūko to sit through a scary movie before continuing to tease her during their bath time. A little while later, the girls leave with some umbrellas they borrowed, but soon return after Yūko gets herself dirty again.
